The Hilton San Francisco Union Square occupies three connecting towers off Union Square in the heart of the restaurant, theater, and shopping districts of San Francisco. The guest rooms and suites number 1,908, while the conference space totals more than 135,000 square feet—72 rooms for everything from meetings of the board to trade shows for thousands of attendees.
For planners, the highlights include the Grand Ballroom, which takes up an entire floor (30,000 square feet); the new Golden Gate Meeting Rooms on the lobby level; and the four handsome boardrooms around a central lobby and foyer in the Executive Conference Center. The event staff's seasoned professionals boast over 80 years of combined experience and take great pride in their reputation for quick responses, creative solutions, and the ability to anticipate every need.
Similarly, knowing that even the most demanding schedules deserve a break, the hotel also features a 13,000-square-foot spa, state-of-the-art fitness center, sixteenth floor courtyard with swimming pool and whirlpool, Starbucks cafe, and the Urban Tavern, a “gastropub” and leading light of culinary trends in the city by the bay. For those seeking additional San
Francisco treats to savor, the hotel offers the city's most popular cultural and tourist attractions within blocks of its doorstep. bay.
